[600MRG] Advice needed

[Carmelink]

At https://apps.fcc.gov/oetcf/els/reports/GenericSearch.cfm ask for Disposal Date Range of your choice (use DD/MM/YYYY format), Frequency Range 135.7 -137.8 kHz, Application Status all, Application Type new license.  They have all the winners, 15 years worth; then, click on initial form and/or exhibits for each ham-associated license to see the submission.  Good luck!

Gang, thank you for all your replies to my grounding question. I always learn a 
lot from you guys. There is always someONE (or ten) that has an experience to 
share that gives me great new insight into some phase of ham radio.
Many thanks !!!
